MAIN COMPONENTS
Structure
Realized in galvanized steel sheet, thermally and acoustically
insulated by self-extinguishing panels class 1.
Height reduced to facilitate installation in a horizontal position,
in false ceilings.
The bearing structure contains the tank for collecting and dis-
charging condensate.
Heat exchanger
High efficiency standard with 3 rows, but also available with 4
rows upon request, heat exchangers are made of copper tube and
alluminium fins secured to the tubes by mechanical expansion.
It is fitted with brass manifold and an air valve.The heat exchanger,
usually with left hand water connections can be turned by 180°.
Available upon request high efficiency heat exchanger optimized
for district cooling application.
Fans
Double suction centrifugal fans made with ABS or aluminium,
with statically and dynamically balanced forward-curving blades,
directly coupled to the electric motor.
Electric motor
Single-phase asynchronous multi-speed electric motor with per-
manently connected capacitor and thermal protector, mounted
on vibration-damping supports.
Air filter
Washable air filter, made of acrylic fibre, filtration class G3, ap-
plied on the air intake; may be pulled out from below.
Air inlet
Air intake from the front or bottom of the unit, according to sys-
tem requirements.
Installation example
The bearing structure allows to combine a large range of acces-
sories in suction and air delivery in order to obtain the optimized
unit configuration.
